Hi,
yes, the latest full backup shows files which have been
deleted months ago. At the time of backing up the client
they did not exist on the client!
For testing I did a new "full" backup.
It has the same old files in it :\
So I created a new host (by IP instead of name), copied
the "macosclient.pl" to "$IP.pl", reloaded backuppc and
staarted a new backup on the IP-based host. This backup
now only has the files which really do exists on the client.
Looks like there is something broken in the inventory of
the backups of this host.
Any better idea instead of simply removeing all backups
from this host and start a new series?

Are you saying that your full backup, 666, contains files

Here is my speculation.
Your BackupPC_nightly is configured to traverse only a
portion of the pool each night for all of the machines
backed up and is not proceeding far enough to identify the 0
link count for the now deleted file.
For full backups BackupPC does a comparison of files already
in the pool to those physically on the client and if a file
already exists in the pool, instead of downloading the
entire file again it increments the file count associated
with this machine and moves on. For files that nolonger
exist on the client machine it decrements the file count to
zero but does not immediately delete it from the client pool
count. The next time BackupPC_nightly runs, assuming it
traverses the whole pool, it removes the files that have a
zero count associated with that client.
In the documentation this is covered in the section headed
"BackupPC Design". I had to read this section several times
to understand how BackupPC_nightly works and also the
config.pl related to nightly. My pool is I think very small
so I have the nightly configured to traverse the entire pool
each time it runs at the beginning of the backup schedule
each day.
If I've got this wrong then I think those who do know will
now clarify my miss conception.
